(This if most of this was inspired from Fallout Brotherhood of Steel, but I have edited some things so it doesn't get confusing & I'll just make two parts of this so it doesn't take over 2k words.)

High elder

The high elder is the supreme leader of the entire Teutonic order and as such oversees the other elders. High elders may also honorarily be addressed as "generals".

Known High Elders :
August Wilhelm Heinrich Günther Viktor (1918-1949) [the forth son of Kaiser Wilhelm II]

Alexander Ferdinand Albrecht Achilles Wilhelm Joseph Viktor Karl (1949-1985) (the son of the elder August Wilhelm.)

Otto Eduard Leopold von Bismarck II (1985- current)

Elder

The elders form the order's ruling council. Individual elders are occasionally leaders of localized chapters of the order . Under normal circumstances, the ability to become an elder is reserved for paladins, although there are exceptions, such as Elder Elijah, who was a scribe.

Cleric

Clerics are the religious leaders of the Teutonic order. They are responsible for educating aspirants, anointing new squires and blessing knights with incense before their missions.

Sentinel

Sentinel is a rank used by the East Coast division, ranking between star paladin and elder. Sentinels do not require specific orders and usually conduct operations at their own discretion, with the elder issuing only standing, high-level orders. Sentinels are appointed directly by the chapter's elder, acting as an extension of their will. There is no requirement to appoint a sentinel and many chapters can go for years without one

Paladins

Head paladin

The commander of the paladins, responsible for overseeing their operations and training them. The head paladin may induct other members of the order into the paladins at their discretion, depending on their aptitude.

Senior paladin

Senior paladins are paladins that show promise to become head paladins. They are well respected among other paladins and knights and can greatly increase the morale of soldiers.

Star paladin

Star paladins are paladins who have been recognized by the order for their honor, loyalty, and tenacity in battle. They are given far more freedom (similar to sentinel) in how they conduct operations, although not as much as a sentinel would.

Paladin commander

Paladin commanders are unit leaders in the Eastern division and are well respected among the order's ranks. They are scarcely found in the field, often planning with the other commanders in the order, but when they are, they are a force to be reckoned with, often found with powerful weapons and leading huge forces. They rank only below star paladin, sentinel, and elder

Paladin

Paladins are a class of members of the Teutonic order. They are likened to the scribes of the order as being on the same level, but with a different purpose. They are the protectors of the order, fighting and protecting its interests across the kingdoms, equipped with powerful armor and an array of lethal weapons

Knights

Head knight

The commander of the knights, in charge of all their operations. The order allows for positions to be combined, and one person can be both head knight and head paladin.

Knight commander

Knight commanders are often seen in the field leading shock troopers dropped off of trucks, or in charge of a command post in the area, leading lower ranking knights into battle. They are the highest ranking knights in the order.

Knight captain

Knight captain is a rank used by the East Coast division. Knight captains can be seen holding staff jobs as well as command positions.

Knight sergeant

Knight sergeant is a rank used by the chapter, denoting a position below knight captain. The rank gives command of one or two squads of knights, as well as the command of a base or outpost.

Senior knight

Experienced knights may be promoted to a position of seniority, overseeing the activities of their juniors.

Journeyman knight

(This rank is typically referred to as just Knight.)
Knights are responsible for manufacturing and repairing weapons and other pieces of technology. After many years of service and experience, the best knights are promoted to paladins, the pinnacle of the Order's military. The next rank is senior knight, and finally, the leader of the order is the head knight.

Initiates

Squire

Originally, the rank of squire was a precursor to the rank of initiate. Similarly to initiates, squires were adult members of the order training to become full knights

Aspirant

The rank of aspirant denotes a member of the order who has progressed beyond the level of initiate but has not yet become a squire or a full-fledged knight. Aspirants share many of the same duties as initiates and spend most of their time training or studying under the guidance of more senior members, such as clerics. Aspirants have a variety of responsibilities that range from latrine duty to field operations. When they are deemed worthy, some aspirants are chosen to get anointed as squires, which is seen as an honor, with those lucky enough to receive the promotion being cheered on by their peers.

Senior initiate

Senior initiates are initiates who have completed basic training and move on to more advanced training.

Initiates

Initiate is one of the lowest ranks in the Teutonic order's rank system. The term to indicate a mere trainee as having been initiated into the order, whereas the other two reserve that title until the recruit has completed initial training. The bulk of its new recruits are the offspring of existing members and only rarely are outsiders accepted into the organization, but had actively recruited from among the local population.
